SUPER bargain !This is a such great little fun rifle for the money!Yeah, yeah I know ,I know: " it's no Weihrauch HW90" ( what a sweet primo air rifle though!) but really who cares--it gets your plinking and pesting done for a lot less in two calibers no less !I have seen a review or two suggesting that this air rifle is too loud to be "back yard friendly" . I am pretty sure that those reviewers experienced " dieseling" when the preservative used in new air rifles combusts upon firing a pellet the shot then sounds loud as a 22lr. It is highly recommended that before shooting that you at least patch clean your air rifle bore several times until the patch comes out clean to remove the grease and gunk in the barrel.Otherwise, you will get a loud report!Switching out the barrels is fairly easy, but it will necessitate re-zeroing your scope as the POI is different between the weight and relative fps of the .177 and .22 pellets. Even switching out the .177 and .22 barrels back and forth is bound to throw POI off.To compensate, I left the scope off , using the fixed sights, relying upon old fashioned get-er-done Kentucky windage and Tennessee elevation to make hits--you know, what they call "marksmanship"?Not that I'm the world's best air rifle shot or anything.After I received my Beeman 1022 ,I spent a good portion of the next day trying to break in the rifle just going thru a few hundred .177 and .22 pellets.Probably using between 300 to 400 assorted .177 and .22 cal pellets two see which ones worked best.The BEEMAN 1022 isn't a one hole tack driver but I can regularly center hit the red out of a Gamo 8 inch shoot n see type target " minute of tree-rat " sized groups using Crosman Premier Hollowpoint .22 Cal, 14.3 gr pellets at 25 yards. The Crosman Premier Piranha .177 Cal, 10.5 gr did a little bit better staying pretty tight at 25 yards as well. Unfortunately my favorite pellet, .22 cal GAMO Rockets, were giving me 3 inch groups.Maybe after this rifle settles in, I will leave either the .177 or .22 barrel on depending on which one shoots the best. YMMV but my velocities were 625 fps in .177 and 560 in .22. with the pellets mentioned. There is one thing I found quite amusing on the packaging of the rifle. Depending on which side of the carton you are looking at the specs for the fps in .177 and .22 are way out of wack! The front of the carton specs " Velocity : Up to 1,000 fps in .22 cal. with Alloy pellets and up to 750 fps in .177 with alloy pellets" Then on the bottom of the carton: " Velocity : up to 1,000 fps in .177 cal (with alloy pellets) Up to 750 fps in .177 cal ( with alloy pellets)" The side of the carton clears things up with the usual marketing specs: " VELOCITY up to 1,000 fps in .177 cal with Alloy pellets and up to 750 fps in .22 cal with Alloy pellets". But wait , there's more !.......................The manual strongly advises against using lightweight , i.e alloy pellets ! : " Also not recommended: plastic sheathed steel or zinc pellets"--oh well guess there goes my 1,000 fps in .177 or is it .22 or is it .177 and .177? or .177 at 750fps and 1,000fps or..Bottom line this is a great little rifle that will give you a lot of bang for your buck.
